When you source automotive metal parts globally, the distance between tool design and final quality can feel enormous. A die built in one place, parts stamped in another, and inspection handled by a third party — each handoff introduces risk, delay, and cost. That is why more procurement professionals are consolidating their supply chain around partners who can deliver automotive stamping dies, production stamping, and quality inspection under one roof. DA Stamping (Linhai Dian Mould Co., Ltd.), based in Taizhou, Zhejiang, China, has been doing exactly that for more than 20 years.

The One-Stop Advantage

DA Stamping was founded in 2003 and has grown into a 50,000 m² modern facility with a dedicated 4,000 m² die workshop. The company employs approximately 110 people, including 35 experienced die designers and technicians, and produces roughly 2,000 sets of medium and small stamping dies per year, with an annual die turnover of around RMB 50 million. A new 35,000 m² facility featuring additional press and coating lines is already in the pipeline, signaling a clear commitment to expansion.

What sets DA Stamping apart is its ability to manage the entire manufacturing chain — from tool design and fabrication to high-volume stamping, welding, assembly, and inspection. This end-to-end capability eliminates the coordination headaches that plague multi-vendor supply chains and ensures that every part is traceable back to a single, accountable source.

Core Capabilities at a Glance

Precision Tooling for Complex Automotive Parts

The foundation of any quality stamped part is the die that produces it. DA Stamping specializes in progressive, transfer, and tandem dies for medium to large, complex automotive components. The company's die designers work with 2D drawings, 3D data, or physical samples to engineer tooling that meets tight tolerances while optimizing material utilization and cycle time.

Application areas span body-in-white panels, door hinge reinforcements, seat structures, instrument-panel brackets, floor-pan cross members, chassis components, and exhaust-system heat shields. Whether you need a high-speed progressive die for a small bracket or a transfer die for a deep-drawn structural part, the engineering team has the portfolio depth to deliver.

Quality Assurance Through Precision checking fixture Solutions

In automotive manufacturing, verifying that a stamped part matches its design dimensions is just as critical as the stamping process itself. DA Stamping designs and builds high-precision checking fixtures — custom inspection tools that confirm whether a workpiece conforms to specified tolerances. Unlike general-purpose measurement tools such as calipers or micrometers, a checking fixture allows operators to inspect large volumes of parts quickly and consistently by simply locating the part in the fixture and reading the go/no-go indicators.

The checking fixtures produced by DA Stamping are designed to work as a matched set with the stamping dies, following GD&T principles to ensure that every dimension called out on the engineering drawing is verifiable. This is especially important for complex stamped geometries where individual measurement would be time-consuming and error-prone. By eliminating individual operator variation, the checking fixture system delivers reliable, repeatable quality data that supports both ISO 9001 compliance and IATF 16949-oriented automotive quality practices.

Additional Services: Welding Jigs and Assembly

Beyond tooling and stamping, DA Stamping offers custom welding jigs and fixtures for accurate, repeatable welding and assembly. These fixtures position and hold components during welding, ensuring consistent joint geometry and minimizing distortion. The company's welding jig capabilities support MIG, TIG, and spot-welding processes for automotive sub-assemblies, from seat frames to chassis brackets.

A Track Record That Speaks for Itself

DA Stamping serves OEM customers including KIA, BYD, Toyota, Honda, Suzuki, and Geely, and exports to more than 10 countries. The company operates as a direct factory — not a trading company — which means customers benefit from factory pricing, direct technical communication, and shorter lead times. Typical delivery for steel stamping dies is 30 to 40 days, and approximately 70 days for casting dies, depending on complexity.

The quality management system is certified to ISO 9001, and the company follows IATF 16949-oriented practices throughout its manufacturing and inspection processes. Free metal samples are available for evaluation, with the customer covering freight.
